VS code right click menu new class c#
If you want those options in your right click menu, then you need to install the "C# Extensions" extension from the marketplace.
The link is here
Keep in mind this is just a shortcut extension, it is not actually required.
You can simply choose new file and give it the .cs
extension if you want a new C# file.
It seems "C# Extensions" is no longer maintained. I tried it and it was not reliable. Sometimes it worked, sometimes it didn't.
But there is a similar extension called "VS Sharper for C#", see here.
